New Tripentone Analogs with Antiproliferative Activity

2017

Tripentones represent an interesting class of compounds due to their significant cytotoxicity against different human tumor cells in the submicro-nanomolar range. New tripentone analogs, in which a pyridine moiety replaces the thiophene ring originating the fused azaindole system endowed with anticancer activity viz 8H-thieno[2,3-b]pyrrolizinones, were efficiently synthesized in four steps with fair overall yields (34–57%). All tripentone derivatives were tested in the range of 0.1–100 μM for cytotoxicity against two human tumor cell lines, HCT-116 (human colorectal carcinoma) and MCF-7 (human breast cancer). The most active derivative, with GI50 values of 4.25 µM and 20.73 µM for HCT-116 a…

Advanced Systems for Skin Delivery of Cyanocobalamin: A Model Molecule for > 1 kDa Drugs

2022

La optimización de la biodisponibilidad de los fármacos brinda una segunda oportunidad a los fármacos que, por diversas razones, no pueden ejercer un efecto terapéutico óptimo. La piel se ha utilizado como plataforma para administrar medicamentos desde la antigüedad y, en la actualidad, se sigue considerando como una de las principales alternativas a la vía oral. Sin embargo, como interfaz entre el organismo y el medio ambiente externo, la capa más externa de la piel (estrato córneo) impide la entrada de sustancias. Esta oposición es de gran importancia para las moléculas de gran tamaño, considerando 500 Da como el tamaño máximo para que una molécula difunda de forma natural a través de la …

Central nervous system involvement at first relapse in patients with acute promyelocytic leukemia treated with all-trans retinoic acid and anthracycl…

2009

Background The prevalence of and risk factors for central nervous system recurrence in patients with acute promyelocytic leukemia are not well established and remain a controversial matter. Design and Methods Between 1996 and 2005, 739 patients with newly diagnosed acute promyelocytic leukemia enrolled in two consecutive trials (PETHEMA LPA96 and LPA99) received induction therapy-with all-trans retinoic acid and idarubicin. Consolidation therapy comprised three courses of anthracycline monochemotherapy (LPA96), with all-trans retinoic acid and reinforced doses of idarubicin in patients with an intermediate or high risk of relapse (LPA99). Central nervous system prophylaxis was not given. Re…

Safety Evaluation of α-Lipoic Acid Supplementation: A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Clinical Studies

2020

Alpha-lipoic acid (ALA) is a natural short-chain fatty acid that has attracted great attention in recent years as an antioxidant molecule. However, some concerns have been recently raised regarding its safety profile. To address the issue, we aimed to assess ALA safety profile through a systematic review of the literature and a meta-analysis of the available randomized placebo-controlled clinical studies. The literature search included EMBASE, PubMed Medline, SCOPUS, Google Scholar, and ISI Web of Science by Clarivate databases up to 15th August 2020. Data were pooled from 71 clinical studies, comprising 155 treatment arms, which included 4749 subjects with 2558 subjects treated with ALA an…

Patients' and physicians' preferences for type 2 diabetes mellitus treatments in Spain and Portugal: a discrete choice experiment.

2015

Objective: To assess Spanish and Portuguese patients' and physicians' preferences regarding type 2 diabetes mellitus (T2DM) treatments and the monthly willingness to pay (WTP) to gain benefits or avoid side effects. Methods: An observational, multicenter, exploratory study focused on routine clinical practice in Spain and Portugal. Physicians were recruited from multiple hospitals and outpatient clinics, while patients were recruited from eleven centers operating in the public health care system in different autonomous communities in Spain and Portugal. Preferences were measured via a discrete choice experiment by rating multiple T2DM medication attributes. Data were analyzed using the cond…

Anàlisi psicosocial del consum alcohòlic entre els adolescents

2006

En aquest article són estudiats 1.100 adolescents d'ambdós gèneres, escolaritzats a centres educatius de la ciutat de València, amb la fi nalitat de determinar les relacions existents entre el consum de begudes alcohòliques i una sèrie de variables psicosocials hipotèticament vinculades a aquest consum: socialització familiar, actituds envers l'alcohol, valors socials, informació sobre els efectes de l'alcohol i consum en els grups d'infl uència. En funció dels resultats obtinguts, els subjectes van ser assignats a tres clusters de consum alcohòlic: abstemis, consumidors moderats i consumidors abusius. S'hi va aplicar una anàlisi discriminant, els resultats de la qual indiquen que el consum…
